    • An illumination system and a projection system incorporating same are disclosed. The illumination system includes a two-dimensional array of independently operable light sources. Each light source illuminates substantially the entire active area of a pixelated optical light modulator. Each light source emits light in different emission directions. Each emission direction is directed to a respective location in the active area. Each pixel in the active area is illuminated by an incident cone of light from the two-dimensional array of independently operable light sources. The cone has a cone angle and includes at least one light ray from each light source. The cone angle of at least one such cone of light can be controlled by adjusting the intensity of one or more of the independently operable light sources.

    • A polarization converter for polarizing a light beam by converting all light waves to the same orientation comprises 1) a first beam dividing matrix of refractory material for dividing a single, large light beam into smaller sub-beam 2) a second beam focusing matrix for polarizing select portions of the sub-beams, and 3) a series of narrow and shallow polarizing cells. The second beam focusing matrix further comprises a plurality of concave lenses for redirecting each sub-beam and quarter wave retarders disposed in alignment with, and adjacent to, the reflective side of an equal plurality of mirror segments. The polarizing cells include either a first beamsplitter or a second beamsplitter, where the first beamsplitters and second beamsplitters are disposed in opposing diagonal fashion and in an alternating manner. Lightwaves of a selected polarization pass directly through the first beamsplitter and out of the polarizing cell, while all other lightwaves are horizontally reflected by the first beamsplitter and directed onto the second beamsplitter where they are redirected toward the quarter wave retarder. The reflected light passes through the quarter wave retarder, reflects off of the mirror and again passes through the quarter wave retarder. The wavelength of the light is retarded ninety degrees as a result of the two passes through the quarter-wave retarder, thus re-orienting the light to the selected orientation. The re-oriented p-waves pass through the second beamsplitter and exit the polarizing cell, join the original p-waves exiting the polarizing cells, and form a beam of polarized light.
    • 用于通过将所有光波转换成相同取向来使光束偏振的偏振转换器包括1)用于将单个大光束分成较小子光束的耐火材料的第一光束分割矩阵2)用于偏振的第二光束聚焦矩阵 选择子光束的部分,以及3)一系列窄而浅的偏振光。 第二光束聚焦矩阵还包括多个凹透镜,用于重定向与等量的多个反射镜段的反射侧对准并相邻设置的每个子光束和四分之一波长延迟器。 偏振元件包括第一分束器或第二分束器,其中第一分束器和第二分束器以相对的对角线方式并且以交替方式设置。 所选极化的光波直接通过第一分束器并离开偏振单元,而所有其它光波被第一分束器水平地反射并被引导到第二分束器上,在那里它们被重定向到四分之一波长延迟器。 反射光通过四分之一波长延迟器,反射离开镜子,再次通过四分之一波长延迟器。 作为两次通过四分之一波长延迟器的结果,光的波长延迟了90度,因此将光重新定向到所选取向。 重定向的p波通过第二分束器并离开偏振单元,连接离开偏振单元的原始p波,并形成偏振光束。
